Apologies if this has been asked before - forum search didn't turn anything up. I'm trying to design a specific call flow for incoming calls to a user and cannot seem to crack it. 1 - Ring IP phone and iOS apps simultaneously. 2 - If no answer, call mobile number - cannot use "Ring my mobile simultaneously" as this does not announce the call and the mobile network's voicemail answers the call. 3 - If there is still no answer forward call to another external number (answering service). Would using a ring group be the best way to achieve the above? Problem with this is that I'd like the IP phone to continue ringing... Is it possible to re-direct a ring group to an external number without creating a "dummy" extension for it? It is it possible for a ring group to "cascade" calls? So for example, ring 1, then 1 and 2, then 1, 2 and 3 all at the same time? Thanks!
